Don't search for java command in legacy locations #121

Open mizdebsk opened 2 weeks ago

mizdebsk commented 2 weeks ago

Currently the java command is searched in the following locations under JAVA_HOME:

jre/sh/java - old IBM Java, at least on AIX
jre/bin/java no longer relevant since Jigsaw (Java >= 9)
bin/java - still used

bin/java is the only one currently used. Therefore Javapackages should look for java command only under ${JAVA_HOME}/bin/java and ignore the other two locations.

This will not work for me here if there is only java-1_8_0-openjdk package installed. I have some users that insist using that on some systems :)

fridrich commented 2 weeks ago

OK, if there is no other java-N-openjdk installed, it would work through the /usr/bin/java alternative. But in other situations, it would mean that they have to change their scripts to set it to the jre subdir.

Right, this is scoped for next major release (7.0.0) when we can assume that Java 8 is no longer relevant. On older systems javapackages 6.x can still be used.
